Onsemi has unveiled NTBL045N065SC1, the world’s first TO-Leadless (TOLL) packaged 650V Silicon Carbide (SiC) MOSFET. The MOSFET comes in a compact package and offers enhanced performance with higher efficiency. The component offers better thermal performance, lower gate noise, and lower switching losses.
With advancements in electric vehicles and other high-performance operations, which have high power density levels, the silicon MOSFETs are being replaced by the silicon carbide MOSFET. The new MOSFET offer significant advantages over their silicon predecessors, including enhanced efficiency at high frequencies, lower EMI, higher temperature operation, and greater reliability. Currently, Onsemi is one of the only suppliers of SiC solutions with vertical integration capability including SiC boule growth, substrate, epitaxy, device fabrication, etc.
According to the company, the new TOLL package offers 30% savings in the PCB area over a D2PAK package. With a footprint of just 9.90 mm x 11.68 mm, and a profile of just 2.30 mm, it occupies 60% less volume than the commonly used D2PAK package. Furthermore, the TOLL package offers better thermal performance and lower package inductance (2 nH). It also offers a 60% reduction in turn-on loss (EON) and a lower gate noise due to the Kelvin source configuration. All these features add to provide higher efficiency and better power density, therefore simplifying the PCB design.
“The ability to deliver highly reliable power designs in a small space is becoming a competitive advantage in many areas, including industrial, high-performance power supplies and server applications,” said Asif Jakwani, senior vice president and general manager, Advanced Power Division, onsemi. “Packaging our best-in-class SiC MOSFETs in the TOLL package not only reduces space but enhances performance in many areas such as EMI and reduces losses. The result is a highly reliable and rugged high-performance switching device that will help power designers meet their stringent power design challenges.”
The NTBL045N065SC1 is suitable for demanding applications such as switch-mode power supplies (SMPS), server and telecommunication power supplies, solar inverters, and uninterruptible power supplies (UPS), and energy storage. The device has a maximum operating temperature of 175°C and ultra-low gate charge (QG(tot) = 105 nC) that significantly reduces switching losses.
